Assuming some language-of-thought story is true, can the language of thought include context-sensitive words? Prima facie: it can't, unless thinkers get confused. I develop the point in more detail here, namely why a mind/brain with context-sensitive LoT would normally get confused and what the options are for it to have context-sensitive thoughts without getting confused.
To be precise is to make it as easy as possible for others to prove one wrong. That is what requires courage.
Etre précis consiste à rendre aussi facile que possible aux autres de démontrer qu'on a tort. C'est cela qui requiert du courage.
